1.1 Front Panel Controls and Indicator s
1.1.1 PTT
A front-panel push-to-talk (PTT) button is provided to facilitate bench and field testsand adjustments. The button is a momentary action type. When keyed, audio from theline input is disabled so that a carrier with subtone is transmitted. The front-panelmicrophone input is not enabled in this mode, but it is enabled when the PTT line onthat socket is pulled to ground.
1.1.2 Line
The LINE trimpot is accessible by means of a small screwdriver from the front panel ofthe module. It is used to set the correct sensitivity of the line and direct audio inputs. Itis factory preset to give 60% of rated deviation with an input of -6dBm (388mV RMS)at 1kHz. The level may be measured between pins 6 and 1 on the test socket. Theadjustment range is approximately -30dBm to +10dBm.
An internal jumper provides a coarse adjustment step of 20dB. Between the jumper andthe trimpot, a wide range of input levels may be accommodated.

RF Technology T220 Page 9
2.9 JP16: Direct Digital Input 2 TRANSMITTER INTERNAL JUMPER OPTIONS
2.9 JP16: Direct Digital Input (Rev 4 or Higher )
Some trunking controllers have digital encoding schemes which operate to very lowfrequencies. The elliptical filter, used as a 250Hz low pass filter in the tone section,can cause excessive pulse edge distortion of the trunking controller’s digital signals. Insuch circumstances, JP16 allows a user to bypass the low ad high pass filters in the toneinput section. See also 2.12 - JP22: If direct tone input is selected, then JP22 should beremoved (open).
Condition PositionNormal Tone Input 1-2*Direct Tone Input 2-3
2.10 JP17: Bypass Low Pass Filter (Rev 4 or Higher )
Some trunking controllers have digital encoding schemes that require the low pass filterin the tone input section to be bypassed. JP17 allows this. Normally JP17 is opencircuit. Placing a link across it will bypass the low pass filter.
In conjunction with this change, it sometimes may be necessary, depending upon thetype of trunking controller used, to add a 100K resistor in the place reserved for R157.
2.11 JP19: Alarm Output (Rev 4 or Higher )
The main audio transformer (T1), is connected to the Line IP1 and Line IP4 pins on P3.
These two pins constitute the main audio input for the exciter. The centre taps of theaudio transformer, though, are brought out on Line IP2 and Line IP3. These can beused as alternate audio inputs for larger signals, or to directly access the dc loop sensecircuitry. JP19 allows an alternate use for Line IP2 (pin 7 of P3). In the alternateposition for JP19, the ALARM signal (the signal that drives the ALARM LED itself) isconnected to pin 7 of P3. The ALARM signal when asserted is low active; whenunasserted, it pulls high to +9.4V through an LED and a 680 ohm resistor.
Condition PositionP3, pin7 connects to centre tap of transformer T1 1-2*P3, pin 7 connects to ALARM signal 2-3
Page 10 RF Technology T220
2.13 JP23: Connection of DMTX 2 TRANSMITTER INTERNAL JUMPER OPTIONS
2.12 JP22: Use Tone- as a Direct Digital Input (Rev 4 orHigher )
JP22 is normally shunted with a jumper, which connects Tone- on P3 (pin 18), as thenegative leg of the Tone input pair. Removing this jumper disconnects Tone- from thispath and allows the use of the Tone- pin to be used as a direct digital input. See also2.9 - JP16: If the jumper is removed, then JP16 should be in the alternative position(Direct Tone Input)
2.13 JP23: Connection of DMTX Board (Rev 4 or Higher )
When the DMTX board is connected to an exciter, there is provision for digital or audiomodulation of the reference oscillator and VCO. The digital signal is input via the DB9rear connector and the audio input signal is via the Line inputs on the standard DB25rear panel connector.

4 CHANNEL and TONE FREQUENCY PROGRAMMING
4 Channel and Tone Frequency Programming
Channel and tone frequency programming is most easily accomplished with RFTechnology TecHelp Software or the Service Monitor 2000 software. This softwarecan be run on an IBM compatible PC and provides a number of additional usefulfacilities. DOS and 32-bit versions are available.
TechHelp allows setting of the adaptive noise squelch threshold, provides a simplemeans of calibrating the forward and reverse power detectors, setting the power alarmpreset levels, and enabling transmitter hang time and timeout time limits.TecHelp/Service Monitor can be supplied by your dealer, distributor or by contactingRF Technology directly.
5 Circuit Descr iption
The following descriptions should be read as an aid to understanding the block andschematic diagrams given in the appendix of this manual.
5.1 VCO Section
The Voltage Controlled Oscillator uses a junction FET which oscillates at the requiredtransmitter output frequency. A varactor diode is used by the PLL circuit to keep theoscillator on the desired frequency. Transistor Q20 is used as an active filter to reducethe noise on the oscillator supply voltage. The VCO is keyed ON by themicrocontroller through Q10. It is keyed ON when any of the PTT inputs are active andOFF at all other times.
The VCO output is amplified and buffered by monolithic amplifiers MA2 and MA3before being fed to the PLL IC U6.
Amplifiers MA1, MA4 and MA5 increase the VCO output to approximately 4 mW todrive the power amplifier. MA1 is not switched on until the PLL has locked and hadtime to settle. This prevents any momentary off channel transmission when thetransmitter is keyed.
5.2 PLL Section
Temperature compensated crystal oscillator XO1 is the frequency reference source forthe PLL Synthesizer. The frequency stability of XO1 is better than 1 ppm and it can besynchronized to an external reference for improved stability. External reference optionboard 11/9119 is required when using an external reference.
XO1 is frequency modulated by the processed transmit audio signal from U7b. Thisextends the modulation capability down to a few Hz for sub-audible tones and digitalsquelch codes. A two point modulation scheme is used with the audio also being fed tothe VCO to modulate the higher audio frequencies.
Page 14 RF Technology T220
5.3 Power Amplifier 5 CIRCUIT DESCRIPTION
The 12.8MHz output of XO1 is amplified by Q22 to drive the reference input of thePLL synthesizer IC U6. This IC is a single chip synthesizer which includes a 1.1 GHzpre-scaler, programmable divider, reference divider and phase/frequency detector. Thefrequency data for U6 is supplied through serial data link by the microprocessor.
The phase detector output signals of U6 are used to control two switched currentsources. The output of the positive and negative sources (Q3 and Q6) produces thetuning voltage which is smoothed by the loop filter components to bias the VCOvaractor diode D3.
5.3 Power Amplifier
The 4 mW output from the main board connects to the power amplifier board through ashort miniature 50Ω coaxial cable.
Q2 on the power amplifier board increases the signal to approximately 200 mW. Thebias current of Q2 is controlled by Q1 and the power leveling circuitry to adjust thedrive to the output module U2.
U2 increases the power to 10--30 watts (depending upon options) before it is fed to thedirectional coupler, low pass filter and output connector. The directional couplerdetects the forward and reverse power components and provides proportional dcvoltages which are amplified by U1a and U1b. The forward and reverse voltages fromU1a and U1b are compared to the DC reference voltage from RV1. The difference isamplified by U1c, Q3 and Q4.
The resulting control voltage supplies Q2 through R10, R12 and completes the powerleveling control loop.
5.4 Temperature Protection
Thermistor RT1 on the power amplifier board is used to sense the case temperature ofthe output module U2. If the case temperature rises above 90 degrees C., the voltageacross RT1 will increase and transistor Q5 will be turned on. This reduces the dcreference voltage to the power regulator which in turn reduces the outpower by 6-10dB.
5.5 600ΩLine Input
The 600Ω balanced line input connects to line isolation transformer T1. T1 has two150Ω primary windings which are normally connected in series for 600Ω lines. Thedual primary windings can be used to provide DC loop PTT signaling or a 2/4 wirehybrid connection. All four leads are available at the rear panel system connector.
The secondary of T1 can be terminated with an internal 600Ω load through JP5 or leftun-terminated in high impedance applications.
RF Technology T220 Page 15
5 CIRCUIT DESCRIPTION 5.6 Direct Coupled Audio Input
5.6 Direct Coupled Audio Input
A high impedance (10kΩ) direct AC coupled input is available at the system connector.The direct coupled input connects to U9a which is configured as a unity gain bridgeamplifier.
The bridge configuration allows audio signal inversion by interchanging the positiveand negative inputs and minimizes ground loop problems. Both inputs should beconnected, with one lead going to the source output pin and the other connected to thesource audio ground.
5.7 Local Microphone Input
The local microphone input is provided for use with a standard low impedance dynamicmicrophone. The microphone output is amplified by U9a before connecting to analogswitch U10a. U10b inverts the local microphone PTT input to switch U10a ON whenthe microphone PTT button is pressed. U10a is OFF at all other times.
The local microphone audio has priority over the other inputs. Activation of the localmicrophone PTT input switches OFF the audio from the line or direct inputs throughD16 and U10c.
5.8 CTCSS and Tone Filter
The CTCSS encoder module H1, under control of the main microprocessor U13, canencode all 38 E.I.A.\ tones and (on some models) additional commonly-used tones.
The tone output of H1 connects to jumper JP8 which is used to select either H1 or anexternal tone source. The selected source is coupled to U9c which is a balanced inputunity gain amplifier. The buffered tone from U9c is fed to 300 Hz low pass filter U7c.RV3, the tone deviation trimmer, is used to adjust the level of the tone from U7c beforeit is combined with the voice audio signal in the summing amplifier U7a.
For some trunking controllers, it is necessary to increase the level of tone signalgenerated. For these trunking controllers an extra resistor of value 100K is solderedinto the normally vacant location denoted on the PCB as R157. This increases the gainfrom the tone input by a factor of 5.7 (15dBm).
The low pass filter can be bypassed by inserting a link onto Jumper JP17.
Back to back diodes D4 and D5 limit the maximum tone signal amplitude to preventexcessive tone deviation when external tone sources are used.
The high and low pass filters, and the limiter can all be bypassed by choosing the nondefault position for jumper JP16, and. as well, removing the link from JP22. Thisconnects the TONE - pin of P3 directly into the summing amplifier U7a.
Page 16 RF Technology T220
5.8 Audio Signal Processing 5 CIRCUIT DESCRIPTION
5.9 Audio Signal Processing
Jumper JP4 selects either the line or direct input source. The selected source is thenconnected to JP6. JP6 can be removed to provide 20 dB attenuation when the inputlevel is above 10 dBm to expand the useful range of the line level trimmer RV4. Thewiper of RV4 is coupled to the input of the input amplifier U9d. U9d provides avoltage gain of ten before connecting to the input of analog switch U10c.
The outputs of U10a and U10c are connected to the frequency response shapingnetworks C52, R133 (for 750µs pre-emphasis) and C61, R55 (for flat response). JP7selects the pre-emphasised or flat response.
The audio signal is further amplified 100 times by U7d. U7d also provides thesymmetrical clipping required to limit the maximum deviation. The output level fromU7d is adjusted by RV1, the deviation adjustment, before being combined with thetone audio signal in the summing amplifier U7a.
The composite audio from U7a is fed through the 3Khz low pass filter U7b. When thelinks on JP23 are in their default state, the filtered audio is coupled to the TCXOvoltage tuning input and the modulation balance trimmer RV2. RV2,R99 and R98 attenuate the modulation signal before applying it to the VCO viavaractor D3.
When a DMTX board option is required, jumper JP23 allows the audio paths to be re-routed. The DMTX board provides for an external digital modulation input signal.When the two links on JP23 are positioned in the middle of the 6 pin header, the audiofrom the exciter is passed to the DMTX board via pin 5 of JP5, where the signal isconditioned and then returned from the DMTX board via pin 2 of JP15, and passed tothe two modulation points.
RV2 adjusts level of the audio used to modulate the VCO. This primarily effects thedeviation of audio frequencies above 500 Hz. RV2 is used to balance the high andlow frequency deviation to obtain a flat frequency response relative to the desiredcharacteristic.
5.10 PTT and DC Remote Control
Two main PTT inputs are provided. The first, a direct logic level input, is connectedto pin 3 of the system connector. The transmitter can be keyed by applying a logiclow or ground on pin 3. Pin 3 connects to the PTT logic and microprocessor throughD10.
DC current loop control can be used for remote PTT operation. The current loop canbe configured by JP9, JP10 and JP11 for use with either a remote free switch or aremote switched source.
RF Technology T220 Page 17
5 CIRCUIT DESCRIPTION 5.11 Microprocessor Controller
Opto-isolator ISO1 is used to isolate the loop current signal from the transmitter PTTlogic. The loop current passes through the input of ISO1 and the output of ISO1connects to the PTT logic.
A bridge consisting of diodes D6, D8, D9 and D14 ensures correct operation regardlessof the current polarity. Q17 limits the current and D7 limits the voltage input to ISO1.Any low voltage current source capable of providing 2 mA at 4 V or switching circuitwith less than 4.8kΩ loop resistance can be used to switch the DC loop.
The test PTT button on the front panel and the local microphone PTT button will alsokey the transmitter. Both of these also mute the line audio input. The microphone linealso enables that audio input.
A DMTX board can also cause the exciter to key up. When a TX (or TTL_TX) signalis received by the DMTX board, it pulls pin 6 of JP15 low, which, in turn asserts thePTT_WIRE_OR signal, causing the microprocessor (U13) to key the exciter up.
5.11 Microprocessor Controller
The microprocessor controller circuit uses an single-chip eight bit processor and severalsupport chips. The processor U13 includes non-volatile EE memory for channelfrequencies, tones, and other information. It also has an asynchronous serial port, asynchronous serial port and an eight bit analogue to digital converter.
The program is stored in U5, a CMOS EPROM. U4 is an address latch for the low orderaddress bits. U2 is used to read the channel select lines onto the data bus. U11 is anaddress decoder for U5 and U2. U3 is a supervisory chip, which keeps the processorreset unless the +5 Volt supply is within operating limits. U1 translates theasynchronous serial port data to standard RS232 levels.
The analogue to digital converter is used to measure the forward and reverse power,tuning voltage and dc supply voltage.
If the processor detects that the PTT_WIRE_OR signal is asserted low, it will attempt tokey the exciter up. It will first attempt to key the VCO through Q10, and if the LD pingoes high, it will switch the 9.2 Volt transmit line through Q14 and Q16. AssertingQ16 has the effect of also asserting the yellow Tx LED (D12) on the front panel,enabling the local 25W power amplifier, and causing the T/R Relay output to be pulledlow. D24 is 30 volt zener which protects Q25 from both excessive voltages or reversevoltages.
Should there be a problem with either the tuning volts, or the battery voltage, the VCOlocking, the forward power, or the reverse power, the microprocessor will assert theALARM LED through Q1. Depending on the setting of Jumper JP19, the ALARMsignal can be brought out on pin 7 of P3.
Page 18 RF Technology T220
5.12 Voltage Regulator 5 CIRCUIT DESCRIPTION
5.12 Voltage Regulator
The dc input voltage is regulated down to 9.4 Vdc by a discrete regulator circuit. Theseries pass transistor Q23 is driven by error amplifiers Q8 and Q18. Q9 is used to startup the regulator and once the circuit turns on, it plays no further part in the operation.
The +5 Volt supply for the logic circuits is provided by an integrated circuit regulatorU14 which is run from the regulated 9.4 Volt supply.
Jumper JP18 is not normally fitted to the board, and is bridged with a 12mil track on thecomponent side of the board. It is provided so that the 9.4V load can be isolated fromthe supply by the service department to aid in fault finding.
Jumpers JP20 and JP21 are also not normally fitted on the board, and are usuallybridged with as12mil track on the component side. They allow U14 to be isolated fromits input, or its output or both.
6 Field Alignment Procedure
The procedures given below may be used to align the transmitter in the field. Normally,alignment is only required when changing operating frequencies, or after componentreplacement.
The procedures below do not constitute an exhaustive test or a complete alignment ofthe module, but if successfully carried out are adequate in most circumstances.
TCXO calibration may be periodically required owing to normal quartz crystal aging. Adrift of 1ppm/year is to be expected.
Each alignment phase assumes that the preceding phase has been successfully carriedout, or at least that the module is already in properly aligned state with respect topreceding conditions.
6.1 Standard Test Condition
The following equipment and conditions are assumed unless stated otherwise:
• AF signal generator with 600Ω impedance, 150--3000Hz frequency range, withlevel set to 387mV RMS.
• Power supply set to 13.8Vdc, with a current capability of >5A.
• RF 50Ω load, 30W rated, return loss <-20dB.
• Jumpers set to factory default positions.

7.1 Overall Descr iption
The transmitter is a frequency synthesized, narrow band FM unit, normally used todrive a 100 watt amplifier. It can also be used alone in lower power applications from 2to 25W. All necessary control and 600 ohm line interface circuitry is included.
7.1.1 Channel Capacity
Although most applications are single channel, it can be programmed for up to 100channels, numbered 0--99. This is to provide the capability of programming allchannels into all of the transmitters used at a given site. Where this facility is used inconjunction with channel-setting in the rack, exciter modules may be ``hot-jockeyed'' orused interchangeably. This can be convenient in maintenance situations.
7.1.2 CTCSS
Full EIA subtone capability is built into the modules. The CTCSS tone can beprogrammed for each channel. This means that each channel number can represent aunique RF and tone frequency combination.
2. Be sure to set the power below the rated maximum for the model of transmitter. If in doubt, allow1.0dB cable and connector losses, and assume that the maximum rated power is 30W. This means nomore than 24W at the end of a 1m length of test cable. This pessimistic procedure is safe on all modelsmanufactured at the time of writing.

7.1.3 Channel Programming 7 SPECIFICATIONS
7.1.3 Channel Programming
The channel information is stored in non-volatile memory and can be programmed viathe front panel test connector using a PC and RF Technology software.
7.1.4 Channel Selection
Channel selection is by eight channel select lines. These are available through the rearpanel connector. Internal presetting is also possible. The default (open-circuit) state is toselect channel 00.
A BCD active high code applied to the lines selects the required channel. This can besupplied by pre-wiring the rack connector so that each rack position is dedicated to afixed channel. Alternatively, thumb-wheel switch panels are available.
7.1.5. Micropr ocessor
A microprocessor is used to control the synthesizer, tone squelch, PTT function andfacilitate channel frequency programming. With the standard software, RF Technologymodules also provide fault monitoring and reporting.
7.2 Physical Configuration
The transmitter is designed to fit in a 19 inch rack mounted sub-frame. The installedheight is 4 RU (178 mm) and the depth is 350 mm. The transmitter is 63.5 mm or twoEclipse modules wide.

Most Eclipse transmitter modules contain two PCBs, a motherboard with the controland signal generation circuitry (the exciter board), and an RF Power Amplifier board.Certain models are equipped with optional functions on piggyback PCBs atop theexciter motherboard. The exciter PCB typically has a few components whose valuesvary from model to model depending upon operating frequency and local regulatoryconstraints. The RF PA PCB varies from model to model but to a greater extent. Atleast two different PCB layouts, and numerous variations, exist. This manual presentsthe circuits and parts lists for two representative variants. When ordering spare parts besure to specify the model exactly, in case the part you require is different in value fromthat specified in this manual.
Older models (predating this manual) may not be covered by this manual. However,advances are evolutionary, and the information in this manual will be sufficient in mostcases to permit understanding and servicing of all models, past and present.
Versions of more detailed circuit schematics, printed on A3 paper, may be inserted orbound with this manual towards the end. It is sometimes easier to work with these fold-out diagrams because of their larger format. In case the inserts/fold-outs are missing ordamaged, the reader is advised that information in the figures included with the textshould be identical.
